This comes up as a topic of conversation when sister comes into brother’s room to hang out late one night. Sister ends up admitting she couldn’t get to bed because she’s been so horny; brother admits he plays video games non-stop for the same reason - to ward off the horniness. Playfully showing brother her hard, horny nipples turns into mutual masturbation, which turns into an awkward blowjob, which turns into awkwardly grinding genitals together; finally sister is desperate to just go through with it and tells brother to just put it in her. In episode two, we see that brother and sister are more physically comfortable with each other, sister teasing him flirtatiously when she’s horny, and generally hanging out together more. This new friendliness between them sparks a couple of raised eyebrows from mom, especially when she walks into the house to find sister sitting on brother’s lap in a mini-skirt (unbeknownst to mom, sister is stuffed with brother’s cock under the mini-skirt, as they were fucking immediately before mom walked in). Brother and sister rush upstairs to finish the job as soon as they can sneak away from mom, ending in a creampie as has become their inadvertent habit. The episode ends on sister disclosing that she’s a few days late on her time of the month but she’s still crossing her fingers. Episode three opens on sister gushing relief that her time of the month has arrived and telling brother they should probably stop doing what they’ve been doing after such a big scare. But it’s not long until sister is horned up again and wearing her tightest, tiniest mini-skirt out to the movies with mom and brother, secretly planning on seducing brother again in the car after the movie. But this time, as they’re getting carried away in the back seat inside the garage, mom comes back out to get something and discovers exactly why her son and daughter have been so uncommonly friendly with each other lately. Mom can’t help but rubberneck at the sight rather than interrupt their passion, and ends up masturbating in the corner - until mom and sister catch each other’s eye, right as brother is creampie-ing sister. Opening on episode four, we don’t know what became of the fact that mom caught her son and daughter passionately fucking each other. We know mom is horny from neglect and jealous of her friend who’s having an affair with a younger man. After a few glasses of wine and a good old fashioned gossip session with her friend, mom indulges in a little vibrator time to blow off steam and fantasize an affair of her own. As mom gets lost in thoughts of a younger man touching her passionately, her mind almost inadvertently wanders to the younger man in the bedroom beside hers - her son - and what she saw him doing to his sister a few days ago. She lets her mind go there. And lets herself walk to her son’s bedroom door to awkwardly ask him for help with some vague thing in the other room. She opens up to him about the fact that she hasn’t been sexually satisfied in her marriage for a long time and would like to sexually fulfilling experience, just once. She offers that she will forget what she saw him and his sister doing in the garage the other day if he’ll oblige her. So he does. Mom doesn’t face him at first, so she doesn’t have to look at what she’s doing. But by the end, mom’s eyes are rolling into the back of her head with multiple orgasms, desperate for more. So many more that she ends up working a huge dripping creampie out of her son.
